AWE Tuning uses computer-aided design (CAD) tools to design each of their products to ensure that there is no design flaws before prototyping their products. Each AWE Tuning performance part goes through a rigorous design process where the CAD renderings are done over and over again to ensure that their parts are unlocking maximum power. After designing their products with CAD tools,AWE Tuning tests all their parts on the track and on their in-house dynamometer to help show you what real world performance gains to expect. If a product does not work as well as AWE Tuning would like, they start the process all over again using what they learned from the previous prototype. Every step of the manufacturing process is done in-house to ensure the best quality products for your car. It's this kind of commitment that you should look for in a company when it comes to the performance of your VW, Audi or Porsche.
